Generation of OAM radio waves using slot antenna array

Abstract

This paper discusses a novel and a practical method to generate radio beams carrying Orbital Angular Momentum (OAM) by using slot antenna array. Different modes of OAM waves can be produced by keeping a constant phase delay between adjacent feed elements. This slot antenna array is designed and simulated at 7.8 GHz by using full wave simulator. Moreover, the mutual coupling between elements will be discussed in this paper.
